I was given a 220VAC 50Amp welder.
I have 30Amp 220VAC portable generator.

I want to have the generator run the welder.
Yes. I know. 50Amps is more than 30Amps.

But I'm hoping welding can work at lower than max.
Can it?

Second question, if the first answer is yes, at lower outputs.

The welder male plug seems to be a NEMA 6-50P.
The generator female receptacle is an L14-30R.

My first thought is to find a NEMA 6-50R to L14-30P adapter.
But I can't find them (probably due to the amperage mismatch).

OK. What's next best?

I can find a NEMA 6-50R (which the welder can plug into) to NEMA L6-30P,
which is a 30 Amp Locking Male Plug to 50 Amp Female Receptacle Adapter.

Notice that's 50 amps to 30 amps, so that's not always a problem I guess.
But then I need a NEMA L6-30R to NEMA L14-30P. Which also exists.

Somehow they deal with both the number of wires difference
a. Some have a neutral, some don't
b. All have two hots
c. All have one ground

And they deal with the current difference (knowing that the welder will
have to be set to not full duty of course to keep it below 30 amps).

Will it work to connect a 220VAC welder to a 220VAC generator?
Is there a better way?
